【Abstract】 The applications of ion beam technology on the wheat breedings were elucidated,the principles and methods of breedings through ion beam induced mutation and ion beam mediated transgene were summarized and the parameters involved in wheat breedings in detall ware described.The new genetic laws observed recently in the ion beam induced wheat,and the advance in wheat breedings through ion beam mediated transfer of null DNA molecule,were also presented thus pointing out the critically unsolved questions and perspectives of ion beam technology in the field of wheat breedings.更多还原
